' 25 Claims. (01. 242-81) This invention relates to a paper winder and more particularly to an attachment for paper rewinders for removing the winder shaft from the wound rolls of paper, preferably'in combination with roll ejecting and shaft transfer mechanisms.

It has heretofore been proposed, because of the increased size and weight of paper rolls as produced on modern winding equipment, to provide semi-automatic mechanism for ejecting the wound rolls of paper from their winding position on the winder drums into a suitable receiving position. I have already described and claimed various types of suitable roll ejecting 5 mechanisms in my U. s. Patents Nos. 1,870,224

and 1,870,225 granted August 9, 1932, and my" copending application, SerialNo. 524,439, filed March 23, 1931.

The present invention relates to further im- 'provements in the'mechanical handling'of the wound rolls and their winder shafts, for use either in conjunction with the roll ejecting mechanisms or for separate use as an attachment'to paper rewinders and the like. The com- 5 bined 'use with roll ejecting mechanisms of my previous invention of my present invention for mechanically pulling the winder shaft from the wound roll and for semi-automatically returning the winder shaft for reuse greatly simplifies the operation of modern, wide rewinders and reduces the amount of necessary manual labor to an absolute minimum. Such combination of mechanisms also largely reduces the risks and.

hazards incident to the operation of paperrewinders.

It is therefore an object of this invention to.

It .is a further important object of this invention to provide novel, and semi-automatic attachments for a paper rewinder that are simple and rugged in construction and that resuit in an increased e'fllciency and ease of operation.

Other and further important objects of this invention will be apparent-from the disclosures in the specification and the accompanying drawings. f v invention (in a preferred form) is illustrated in the drawings and hereinafter more p fully describe'dj On the drawings: a I

As shownon the drawings:

The reference numeral ,1 indicates as a whole a paper rewinder of essentially the same construction as that shown in my pendingv applica tion entitled Paper rewinder, U. S. Serial No. 524,439, filed March 23, 1931, It will be understood that many of the details of construction of the rewinder itself constitute merelystandard construction and form no partof the present in vention. 'Therefore, only so much of the con struction of the rewinder as is necessary to an understanding of the present invention will ,be

here described.

Said rewinder 1 (Figures 1, 2 and a) comupstanding portions 3 extending therefromand securedtogether in spaced relation by suitable means, including a tubular cross member 85 and a transversely'extending channel beam 4.

A pair of spaced under drums15 and 6 are suitably journal ed at their respective ends, in bearing housings '7 and 8, which, in turn, mounted upon the base portions 2. Said under "drums 5 and 6 are suitably,driven in the same direction to wind a web of paper, indicated by a dotted line at "148, upon .a winder shaft 9 prises a pair of end supporting bases 2 having PATENT OFFICE that is rotatedby surface-contact between the web of paper and the surfaces of the driven under drums.

Said winder shaft 9, when in operative -position, is held at its ends in releasable clamping members 10. Said clamping members form elements of members 11 that are suitably mounted for vertical sliding movement in guide- A slitting mechanism indicated as a whole by the reference numeral 15, and including rotary slitters 16, is providedfor slitting the responding lengths.

web of paper into the desired widths as it comes from the paper 'machine. The paper is slit while it 'is being wound upon cores 147 of cor-- The cores 147. are mounted on the solid winding shaft 9 in the usual manner, but when a collapsible winder shaft is employed, no cores are used.

Up to this point, merely old or standard rewinder construction has been described. According to my present invention, a roll ejecting mechanism, indicated as a whole by the reference numeral 17 and best shown in Figure 3, is associated with the under drums 5 and 6 to eject the wound roll and associated winder shaft from operative position with respect to the under drums. Said roll ejecting mechanism comprises a pair of arcuate shaped arms 18 pivotally mounted upon a cross shaft 19 that extends beneath the under drums 5 and 6 between the base frames 2. Each of said pivotally mounted arms 18 is provided on its rear up standing portion 28 with ratchet teeth 21 for engagement-with a spur gear 22 secured upon adriven cross shaft 23. A roller 24 is journaled at its ends on the free ends of the portions 28. Each of the arms 18 is also provided with a forward upstanding portion 25, rigidly joined to the corresponding arm, as at 26, near the pivotally mounted end of said-arm. Each of said upstandingportions 25 is connected by means of a link 2'7 integral with the portion 25 and pivotally connected to the correspond ing rear, upstanding portion 28 as at 146, whereby tobra'ce said upstanding portions 25. At the free end of each of said upstanding portions 25, there is pivoted, as at 29, a dependent hook member 30.

The channel beam 4 positioned in front of the under drum 6 is provided at its ends with brackets 31 (Fig. 1), or with integrally formed recesses 32 (Fig. 3), forming sockets 33 for the reception of the ends of a spare winder shaft 9a.

The roll ejecting mechanism just described not only serves to eject the wound roll of paper,

.able source of power (not shown) and through the intermeshing gears 22 and ratchet teeth 21, the 18 are swung upwardly until the roller 24 comes in contact with the roll of paper 34. Continued upward movement of the arms .crown of the forward under drum 6, until it paper 34 and associated winder shaft 9 out from between the under drums 5 and 6 and over the 80 rolls onto a receiving platform 35. Said wound roll of paper then rolls over the spare winder drum 9a onto a sloping platform 36 and is delivered onto the shaft pulling mechanism, indicatd generally by the reference numeral 37 and more fully described hereinafter.

As the roll ejecting arms 18 move in the manner just described, the hook members 30, dependent from the upstanding portions 25, move forwardly until recessed portions 39 on said upstanding portions 25 abutthe shaft 38 of the forward under drum 6. Said hook members may then be manually swung under the spare winder shaft 9a to engage the ends of the same, as indicated in dotted lines in Figure 3. As the roll ejecting arms 18 are moved back into normal position, the hook members 30 drag the spare winder shaft 9a up over the inclined surface 40 of the-sockets 32, over the platform 35 and forward over drum 6 into operative position. The new end of the paper web is then started around the fresh winder shaft 9a and the winding operation continued;

The shaft pulling mechanism 37 comprises a plurality of supporting frames, including end 105 frames 41 and intermediate frames 42, positioned in alignment in front of the rewinder 1 and held in spaced relation by longitudinally extending channel beams 43. Each of the end frames 41 supports, by means of suitable brackets extending therefrom, a pair of spaced, aligned bearing housings 44, in each pair of which is journaled a shaft 45 carrying a pair of sprocket gears 46. A pair of roller type sprocket chains 47 is trained around the corresponding sprocket gears 46 to run lengthwise of the shaft pulling mechanism 37. A plurality of transversely extending cross members 48 are connected to the sprocket chains 47 to provide a roll conveyor 146. Said cross members 48 are provided with concave roll receiving portions 49 (Fig. '7) and certain of said cross members 48 are provided with upstanding cleats or shoes 50 that serve to engage an end of the paper roll 34 in a manner later to be described.

A pair of I-beams 51 extends in parallel spaced relation along thetop of the respective frame members 41 and 42, to which they are suitably secured.- The upper surfaces of these I-beams 51 provide trackways 52 over which the rollers of the sprocket chains 47 run. The platform 36 is pivotally supported from the frame members 42, as at 53, at the proper height to deliver the wound roll 34 onto the traveling conveyor comprising the sprocket chains 4'! and transverse members 48. While on said conveyor 146, the roll rests in the depressions 49 formed in the cross members,

Means for driving the conveyor -146 comprise a motor 54supported on a platform 55 from the channel beams 43. Said motor 54 is connected through a clutch member 56 (Fig. 6) and suit.- able reducing gears 57 and 58 to one of the shafts 45 on which the sprocket gears 46 are keyed or otherwise, secured. Thus, whenthe motor 54"is energized, it serves to drive the conveyor 146 in a direction indicated by arrows in Figure 6 until one of the cleats 50 engages an end of the roll 34.

In order that continued movement of the con- 150 I end '73.

clamping mechanism 60 adjustably mounted by means of a screw mechanism 61 from a stand 62;

Said clamping mechanism 60 is best shown in Figures 8 and 9 and comprises a guide engaging portion 63 and a bracket 64 preferably cast integral therewith. Said bracket 64 is provided with a segmental cylindrical portion 65 that partially houses one end' 66 of the winder shaft 9. A flanged segmental cylindrical socket portion 67 integrally formed on the free end of the bracket 64 serves to partially house a collar 68 such as is usually affixed on a winder shaft end. The flanges 145 of said socket portion 67 prevent more than limited axial movement of the winder shaft 9 when its end66 is engaged by the clamping mechanism.

The clamping mechanism proper comprises a pawl or dog 69 that is pivoted at its apex about a pin 70 extending through spaced lugs 71 formed on the bracket casting 64. One end '72 of said dog 69 passes under the end 66 of the winder shaft 9. The other end, 73, of said dog.

69 is apertured to receive a pin 74 that extends throughan upstanding lug 75 on said bracket 64 and issecured in said lug by means of a nut 76. A spring 77 is mounted under compresssion on the pin 74 between said lug 75 and the dog A handle 78 pivotally secured to the extended free end of the pin 74, as at 79, provides a cam face 80 that permits the spring 77 to cause the release of the dog 72 when the handle 78 is raised. The winder shaft end 66 can then be moved out from between the dog 72 and the segmental cylindrical portions 65 and 67 of the the other of their ends connected by yokes 158 to a cylinder 84 (Figs. 2 and 11). Said cylinder 84 issupported from the cross tube 85 extending between the rewinder frame portions 3 by means of an integral lug 159 on said cylin-v der and a saddle block 160 upon which said lug 1'59 rests (Figs. '4 and 11). A carriage, indicated generally by the reference numeral 86, is mounted for sliding movement on the tracks '83 and for this purpose is provided with shoes or flanges 87 and 88 (Fig 5) that engage the upper and lower faces, respectively, of said track mew bers 83. A piston rod89 is connected at one end, as at 90 (Fig. 4), to the carriage 86 and at its other end to a piston 91 slidable within the cylinder 84. Said cylinder 84 is provided with compressed fluid pipes 92 and 93, which, as bestvalve 95 to separate pipes 96 and 97. Said valve- 95 is of any suitable construction that will per-- mitthe air to be passed from the pipe 94 to either pipe 96 or '97 or to a discharge nipple 98 to permit the discharge of air .from either pipe 96 or '97 when the other pipe is in connection with the pipe 94. Pipe 96 is connected to.

branch piping 100 and 101, which, in turn; are connected by means of suitable fittings to the nipple' 93. Air cocks 102 and 103 are provided in the branch piping 100 and 101, respectively, and the branch pipe 101 includes a check valve 104,

for a purpose later to be described. Pipe 97 is similarly connected to the nipple 92 through branch piping 105 and 106, also similarly provided with a cock'107 and with a cock 108 and check valve 109, respectively. Said pipe 97 is also connected through a cross fitting 110 to a flexible tube 111.

Said flexible tube 111 is connected as at 112 to an openended cylinder 113. (Fig. 5) mounted on the lower end of a vertically adjustable rod 114 from a cross rod 115. Said verticallyadjustable rod 114 extends between two pairs of rollers 116 and 117 (Fig. 4) that are mounted in bifurcated portions 118 and 119, respectively, of the carriage casting 86.

The rod 114 is provided with an upper bifurcated end 120 carrying a roller 121. A rod .122 passes through said bifurcated end 120 and serves as a trackway for the roller 121. Said rod 122 is pivoted as at 123 (Fig. 4) to a bracket 124 secured to the tracks 83'. At its other end, the rod 122 is provided with a pivotally mounted, internally threaded collar 125 through which is threaded a rod 126 (Fig; 1). Said rod 126 is rotatably supported at its lower end from a bracket 127 and is provided with a hand wheel 128 by means of which the rod 122 may be raised or lowered about the pivot point.123.

Said rod 122 comprises a normally substantially horizontal portion 129 lying above the shaft pulling mechanism 37, and an inclined portion 130 that slopes downwardly to the pivot point 123. Said pivot point 123 is substantially directly above the waiting position of the winder shaft 9a.

The cross bar carries at each end a swing ing hook 131 adapted in operating position to engage the winder shaft 9 'of the wound roll of paper 34. As will later be explained, it is necessary at one point in the operation of the shaft pulling mechanism to hold the hooks'131 against swinging movement and this is accomplished by means of air operated mechanism including the cylinder 113. A pair of opposed pistons 132 and 133 (Fig; 5) are mounted in said cylinder 113 on opposite sides of the air connection 112. Piston rods 134 connected to the pistons 132 and 133 extend through a pair of spaced bearing brackets 136 and carry at their outer ends bifurcated members 137 that are adapted to engage the hooks 131 to hold them against swinging movement. A spring 138 is held under compressionbetween a collar 135 secured to each piston rod 134 by means of the set screw 139 and the stationary bearing bracket 136.

Accordingly, when there is no air pressure within the cylinder 113 to force the pistons 132 and 133 outwardly, the compression forces of the springs 138 draw the bifurcated ends 137 out of engagement with the hooks 131. On the other hand, when air is introduced into the cylinder 113 under pressure, the pistons 132 and 133 are forced outwardly to cause the bifurcated ends 137 to engage the hooks 131.

bracket 136 to serve as a stop for limiting the outward movement of the piston rods 134.

The operation of the shaft pulling and shaft transfer mechanisms is as follows. After the roll 34 of paper has reached the desired size on the winder drums 5 and 6, the roll ejecting mechanism 17 is operated, as previously described, to eject the roll 34 from operative relation to the under drums and deliver it onto the conveyor 146 of the shaft pulling mechanism 37. As the roll 34 rolls unto the shaft pulling mechanism, it pushes the hooks 131 ahead of it out of the way, as indicated in Figure 1. The end 66 of the winder shaft 9 moves into the cylindric l socket 65 and the handle 78 is lowered to permit the dog end 72 to come up into engagement with the under surface of the winder shaft end 66. Said winder shaft 9 is then held against axial movement by engagement of the collar 68 with the flange 146 of the socket 67 of the clamping mechanism 60. The motor 54 is then started up to operate the conveyor 146 of the shaft pulling mechanism. Movement of the conveyor brings a cleat 50 into engagement with the end of the wound roll .34, which is thereupon carried along on the conveyor and finally discharged onto a platform 150 made up of a plurality of rollers 151.

If the paper has been wound upon cores 147 on the winder shaft 9, as is customary, the individual rolls of paper with their associated cores merely slip off the end of the winder shaft 9 onto the roller platform 150. If 'a collapsible winder shaft is being used, there are no cores, but the shaft is simply collapsed and the rolls of paper removed in the same manner. The vertical adjustment of the clamping mechanism 60 provided by the threaded rod 61 permits the clamping mechanism to be placed at the correct height for the particular diameter of the roll 34 that is being handled.

It will be noted that at the start of the shaft pulling operation, the hooks 181 are displaced to one side by the roll of paper 34 (Fig. 1), but as the roll 34 is moved axially along the winder shaft 9, first one hook-131 and then the other is allowed to swing down into engagement with the winder shaft 9. By turning the hand wheel 128 one way or the other, the horizontal portion 129 of the trackway 122 can be brought to the proper level such that the hooks 131 engage the shaft 9. The clamping mechanism 60 is then released by raising the handle 78, causing the dog end 72 to drop out of engagement with the end 66 of the winder shaft 9. Said winder shaft 9 is now entirely supported by the hooks 131.

The valve is then adjusted to a position such that compressed air is admitted through the piping 97, branch piping 105 and 106, and nipple 92 to the stufiing box end of the cylinder 84. The plug cocks 107 and 108 are partially closed to cause a throttling effect on the air as it goes into the stuifing box end of the cylinder 84. Consequently, the air first passes unrestrictedly into the flexible tube 111 and through the opening 112 into the cylinder 113. The pistons 132 and 133 in said cylinder 113 are accordingly forced outwardly to bring the bifurcated ends 137 into engagement with the shafts of the hooks 131. Said hooks 131 are thus held against swinging movement to prevent them from being swung backwardly due to inertia and possibly releasing the winder shaft 9 when the carriage 86 starts to move.

The compressed air entering the nipple 92 at the stuffing box end of the cylinder 84 forces the piston 91 toward the outer end of the cylinder, thus moving the carriage 86 and associated hooks 131 toward the spare winder shaft position in the sockets 33. In the course of its travel, the vertical rod 114 associated with the carriage 86 is permitted to drop down as the roller 121 passes onto the inclined portion 130 of the trackway 122. The winder shaft 9 is thus lowered at the end of the travel of the carriage 86 into the spare winder shaft position inthe socket 33. When in this position, the lower ends of the hooks 131 are dropped out of engagement with the winder shaft. At some time during the travel of the carriage 86, fresh cores are threaded onto the winder shaft unless it is of the collapsible type. This can easily be done by manually raising one end of the shaft.

As the compressed air is entering the stufiing box end of the cylinder 84, the piston is forcing out ahead of it the air already in said cylinder and this air passes out through the nipple 93 and piping into the pipe 96. The check valve 104 prevents flow of air through the branch 101. The cock 102 is also slightly closed to cause a throttling effect to thereby prevent a sudden bump as the piston 91 reaches the end of its travel. A bolt 152, provided with an adjusting nut 153, extends through the head end 100 of the cylinder 84 to limit the extreme movement of the piston 91.

Travel of the carriage 86 in the opposite direction is limited by means of a bolt 154 having anadjusting nut 155. Said bolt 154 is threaded through a cross piece 156 that extends between the track members 83 and is adapted to abut a transverse web or lug 157 on the carriage casting when the carriage 86 reaches its extreme point of travel toward the shaft pulling mecha- 119 After the winder shaft has been deposited in the spare winder shaft sockets 33, the valve 95 is properly adjusted to admit air under pressure to the head end of the cylinder 84. The compressed air passes through the pipe 96 and the branch piping 100 and 101 and enters the cylinder 84 through the nipple 93. As the piston 91 is displaced toward the stufiing box end of the cylinder 84, the air is released from said 120 cylinder 84 through the nipple 92, branch 105, pipe 97 and discharge nipple 98. The cock 107 being partially closed, there is a throttling effect similar to that previously described that prevents the piston 91 from bumping at the end of its travel toward the stufiing box end of the cylinder 84. The check valve 109 prevents air from going through the branch piping 106, so that the adjustment of the cocks 107 and 108 can be different, if desired, to get just as quick or as slow speed of travel of the carriage 86 in either direction as is wanted.

The air pressure within the cylinder 113 is also at the same time released through the opening 112 and flexible tube 111 into the pipe 96. Thereupon, the force of the springs 138 acting against the collars 135 serve to retract the bifurcated ends 137 and release the hooks 131.

As the carriage 86 moves back over the track 83 toward the shaft pulling mechanism, the 146 roller 121 travels up over the inclined portion 130 of the trackway 122 onto the horizontal portion 129. The rod 114 is accordingly raised to bring the hooks 131 again into position above the conveyor 146 of the shaft pulling mechanism. The various mechanisms are then again in place for a repetition of the operation.

While I have described my invention in connection with a particular construction of rewinder and of roll ejecting mechanism, it will be 15g understood that the shaft pulling mechanism of my invention has a separate field of usefulness, or can be used with other types of re-' winders and roll ejecting mechanism. For instance, I have described and claimed in my co pending application- Serial No. 524,435, filed March. 23, 1931, a slightly modified form of roll ejecting device and mechanism for transferring the winder shaft from waiting to winding position that might be employed in place of the corresponding device and mechanism here shown.

The shaft pulling mechanism is particularly useful in connection with the handling of very large rolls of paper or other web material with which relatively heavy winder shafts are used. The use of my semi-automatic mechanisms reduces manual labor to a minimum and also greatly lessens the hazards incidentto the manual handling of heavy rolls of paper and heavy winder shafts.

I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
